Speaking during the Fourth Committee of the UN’s General Assembly, he stressed Spain does not want “to impose the terms of the offer”, calling it “a starting point for negotiations”.

He also insisted Spain “has no intention of interfering in the way of life, customs and traditions of Gibraltarians”.

Gibraltar’s economy would continue to benefit from free access to the EU internal market, particularly the free movement of workers and capitals, he said.

Under the plans Gibraltarians would be able to remain citizens of the EU thanks to a dual nationality.

Mr Oyarzun said that the removal of border controls would boost the economy of the area and help expand the port and airport of Gibraltar, which would be fully integrated into the EU’s aviation network.
